H85AX CNC Diamond Cylinder Honing Machine
Special Version High Production Machine that can move automatically in both X and Y axis for automatic honing offset cylinder blocks and parts. This feature allows use of optional programmable roll over fixture to be able to hone a complete V block automatically – unattended! Includes feature to drain coolant out of block at end of cycle.

A must for cylinder honing! ‘Load’ is used to describe the pressure that the honing stones exert against the cylinder wall during the honing operation. Roughing cycles require higher loads for faster stock removal and finishing cycles require lower loads to reduce distortion. The H85X is programmed with roughing and finishing loads automatically controlling the stone pressure while honing cylinder bores producing the desired geometry and surface finish in every cylinder. Honing time is substantially reduced for maximum productivity and repeatability. 
Monitored Variable Load Control 
H80X Series machines are capable of honing with both Clockwise and Counter Clockwise hone head rotation. Aggressive rough honing may cause metal folding due to porosity that may be present in the bore. Reverse rotation during the finishing or plateau cycle smooths potential folding resulting in improved bore quality and consistency.
